I ran it, and I should not have, now my world view is shaken.

They should be equal and they are not. To be sure I didn't make a mistake I reversed both '<' and still the results are not equal. The world is becoming so weird.

Something with the climate

You didn't change this in TL

int TestL()
{   
   int max1 = INT_MAX-1;
   iStart = GetMicrosecondCount();
   for (int i=0; i<INT_MAX; i++)
      bResult = max1<i;
   iStop = GetMicrosecondCount();
   return int(iStop-iStart);
}

int TestLT()
{
   int max1 = INT_MAX-1;
   iStart = GetMicrosecondCount();
   for (int i=0; i<INT_MAX; i++)
      bResult = max1<i;
   iStop = GetMicrosecondCount();
   return int(iStop-iStart);
}

Here is the output

I have deleted a number of posts.

Please remain civil.

Meztiza Ako:

I'm curious. I changed it for you

Here is the output

I don't have to change anything it's not my code. And <=max1 is exactly the same as <INT_MAX when max1=INT_MAX-1.

This topics is surrealist.

Damn it, it will be hard to reach 100 posts if you delete them
 
Icham Aidibe:

Well those installing MT on Linux were probably using Linux before knowing MT and need it for others tasks.

Back to the topic, 

Is <11 faster than <=10?

My opinion upon is that if there's a difference it's negligible.

Your issue ain't an issue, you're procrastinating, it's a loss of time, funny for someone who wanna gain some, isn't it ?

"Well those installing MT on Linux"

Windows is an insult to any computer enthusiast.

"Your issue ain't an issue"

Glad its currently not an issue for you personally. After all, you didn't start the thread.

 
Joel Protusada:

You will best understand these results if you will read the code I posted.

First run with 100 cycles...

2nd run with 100 cycles...

3rd run...

 Running the exact same code that you posted, I get:


 
He also changed to this, because it's '<' against '<':
   string result = "********* With 100 cycles, "; 
   if(ave<0) result += "(<) is faster than (<)";
   else result += "(<) is faster than (<)";
 
For the timescale of MT4/5, it is pointless most of all if you consider the ping between the computer on which the EA/indicator is running and your broker's server. You may want to optimize you in some other ways...
On another matter, if you work with integers, it will be exactly the same. But, if you work with decimals (float or double for example) it is tricky. If I want to open trades only if the spread is inferior or equal to 1.5 pips, I will prefer if spread<1.6 and not if spread<=1.5.
How many times my condition if was not fulfilled when it should have been or conversely, fulfilled when it shouldn't have been only because of hidden decimals. If you display your spread in a Comment(); instruction, you will probably have 1.50024 or 1.49987.
